EIGRP Questions
Here you will find answers to EIGRP Questions
Question 1
Which two of these are the most accurate characteristics of EIGRP deployment? (Choose two)
A. Provides features for most Ethernet, Frame Relay, and dial-up network deployment types.
B. Provides routing for IPv4, IPv6, Appletalk, and IPX.
C. Provides default hierarchical routing and summarization of a VLSM IP address deployment.
D. Provides quick convergence through neighbor relationships and topology backup routes.
E. Provides the best route selection on combined default metrics of active bandwidth,delay, load, reliability, and MTU parameters.
Answer: B D
Question 2
Your company’s Cisco routers are operating with EIGRP. You need to join networks with an acquisition’s heterogeneous routers at 3 sites, operating with EIGRP and OSPF. Which describes the best practice for routing protocol deployment?
A. apply OSPF throughout both networks
B. apply one-way redistribution exclusively at each location
C. apply two-way redistribution exclusively at each location
D. apply two-way redistribution at each location with a route filter at only one location
E. apply two-way redistribution at each location with a route filter at each location
F. apply EIGRP with the same autonomous system throughout both networks
Answer: E
Question 3
A network is being designed to meet the requirements listed. Within the enterprise network:
All routers are Cisco 3800 Series routers running the latest Cisco IOS release.
The fastest convergence time possible is required.
Unequal cost load-balancing is required.
For Internet connections:
A single link is used to connect to a single ISP.
Which two routing protocols should be used?(Choose two)
A. Use OSPF as the IGP within the enterprise.
B. Use EIGRP as the IGP within the enterprise.
C. Use Internal BGP as the IGP within the enterprise.
D. Use External BGP between the enterprise and the ISP.
E. Use EIGRP between the enterprise and the ISP.
F. Use Static (Default) routing between the enterprise and the ISP.
Answer: B F
Question 4
Which two statements best describe intradomain route summarization? (Choose two)
A. OSPF and RIP automatically summarize at classful network boundaries.
B. EIGRP and OSPF automatically summarize at classful network boundaries.
C. EIGRP and RIP automatically summarize at classful network boundaries.
D. EIGRP and OSPF must be manually configured to summarize at non-classful boundaries.
E. EIGRP and OSPF automatically summarize at non-classful boundaries.
Answer: C D
How can Q4 be correct?
C. EIGRP and RIP automatically summarize at classful network boundaries.
D. EIGRP and OSPF must be manually configured to summarize at non-classful boundaries.
If D is true, then B must be true.
B. EIGRP and OSPF automatically summarize at classful network boundaries.
D. EIGRP and OSPF must be manually configured to summarize at non-classful boundaries.
@Nick.
Eigrp summarize automaticly classfull boundries 10.0.0.0/8 etc. but to summarize nonclassfull boundries you have to do it manually so both answers is the correct ones.
Hope it helped clarify.
In configuring DV protocols, “no auto-summary” command has to be entered to support VLSM. OSPF has no command as such and it is a full classless routing protocol.
Any DV protocols summarize at the classful boundaries and OSPF requires manual summary at the interface level.
Question.
In a network with Enhanced Interior Gateway Routing Protocol (EIGRP) and IGRP using the same autonomous system number, what will happen on the router configured with both protocols?
A. Redistribution occurs automatically.
B. Redistribution is not necessary.
C. EIGRP assumes IGRP is a less capable protocol and overtakes it.
D. Redistribution does not occur automatically.
I think the answer is (D).
Why the proposed answer is (A)? Anyone tried this in the lab? Thanks.
@hisulley:
Cisco IOS Release 12.0 Network Protocols Configuration Guide, Part 1, Configuring EIGRP section:
“EIGRP provides the following features:
•Automatic redistribution—IGRP routes can be automatically redistributed into EIGRP, and EIGRP routes can be automatically redistributed into IGRP. If desired, you can turn off redistribution. You can also completely turn off EIGRP and IGRP on the router or on individual interfaces. “
Wow, Jason. Thanks for the tuogohrh explanation. I figured it was something to the effect of whoever talks first is the OSPF-based path to 10.10.20.0/24, but I wasn’t sure if there was some other higher match going on as well.Thanks again!
Q4 has an interesting point. In the latest versions of IOS the ‘no auto-summary’ is automatically on in EIGRP. This is a good thing and you can see it if you grab a 3400 for example.
This means C is technically a legacy question and wrong!
Which two statements best describe intradomain route summarization?
This question is confusing me :(
can somebody explain or give a resource to read :)
re: hisulley
answer a) redistribution occurs automatically.
100% correct.
it is because both routing protocols understand each others metric.
Can someone explain Q2?
